Safety light curtain provides Type 4 machine guarding with 12 beam channels and a 230 mm protective height. It detects opaque objects down to 25 mm using a 20 mm beam pitch and operates across a 0.3 m to 9 m emitter-to-receiver range. The unit uses 24 V DC power and selectable PNP or NPN open-collector OSSD outputs rated up to 200 mA. It has IP67 and IP65 environmental protection and operates from -10 °C to +55 °C without condensation or icing. The emitter and receiver pair weighs approximately 510 g and uses an infrared LED with an 870 nm peak emission wavelength.
